Merge tag 'io_uring-5.12-2021-03-12' of git://git.kernel.dk/linux-block

Pull io_uring fixes from Jens Axboe:
 "Not quite as small this week as I had hoped, but at least this should
  be the end of it. All the little known issues have been ironed out -
  most of it little stuff, but cancelations being the bigger part. Only
  minor tweaks and/or regular fixes expected beyond this point.

   - Fix the creds tracking for async (io-wq and SQPOLL)

   - Various SQPOLL fixes related to parking, sharing, forking, IOPOLL,
     completions, and life times. Much simpler now.

   - Make IO threads unfreezable by default, on account of a bug report
     that had them spinning on resume. Honestly not quite sure why
     thawing leaves us with a perpetual signal pending (causing the
     spin), but for now make them unfreezable like there were in 5.11
     and prior.

   - Move personality_idr to xarray, solving a use-after-free related to
     removing an entry from the iterator callback. Buffer idr needs the
     same treatment.

   - Re-org around and task vs context tracking, enabling the fixing of
     cancelations, and then cancelation fixes on top.

   - Various little bits of cleanups and hardening, and removal of now
     dead parts"
